Problems solved by technology

[0002] The circular arc core pulling mechanism is widely used in the production of plastic products that require circular arc core pulling. Core mechanism, etc., so it is necessary to invent a motion transformation mechanism with simple structure for arc core pulling
The arc core-pulling mechanism is generally matched with the injection molding machine. The injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds, and often requires additional power outside the injection molding machine to Completing the core-pulling action consumes a lot of energy. Therefore, it is necessary to develop a circular-arc core-pulling mechanism that uses the mold opening force of the injection molding machine to realize the mechanism movement without external power.

Embodiment 1

[0018] as attached Figure 1-2 As shown, in this embodiment, a set of two symmetrical motion transformation guide rail type arc swing core-pulling mechanisms is taken as an example, and any one of the motion transformation guide rail type arc swing core pulling mechanisms includes a guide plate 1 and a guide groove 2 , guide pin 3 and L-shaped swing lever 4.

[0019] The L-shaped swing bar 4 includes a first bar 41 and a second bar 42; one end of the first bar 41 is fixedly connected with an end of the second bar 42, and the connection between the first bar 41 and the second bar 42 is fixed in a fixed position. On the first plane 6 that moves vertically relative to the guide plate 1;

[0020] A mold 5 fixedly connected to the guide plate 1 is provided with a guide groove 2 on the guide block, the guide groove 2 forms a certain angle with the vertical direction, and the top of the guide groove 2 is inclined away from the direction of the second rod 42, and the guide pin is set...

Embodiment 2

[0026] as attached Figure 3-5 As shown, a motion conversion guide rail type arc core-pulling mechanism provided by the present invention is set on an injection molding machine, and the mold 12 with the core-pulling part 11 is placed on the fixed mold part 10 of the injection molding machine. In this embodiment, it is Take a group of two symmetrical rail-type arc swing core-pulling mechanisms as an example, any one of the guide-rail type arc swing core-pulling mechanisms includes a guide plate 70, a guide groove 71, a guide pin 40, an L-shaped swing rod 90, a lock Tight block 20, arc guide block 50 and slide block 30,

[0027] The L-shaped swing rod 90 includes a first rod 91 and a second rod 92; one end of the first rod 91 is fixedly connected to one end of the second rod 92, and the angle between the first rod and the second rod is 30-120 degrees, and The connection between the first rod 91 and the second rod 92 is fixed on the movable mold part 60 of the injection molding ...

Abstract

The invention relates to a motion conversion guide rail type arc core-pulling mechanism, which includes a guide plate, a guide groove, a guide pin and an L-shaped swing rod, wherein: the L-shaped swing rod includes a first rod and a second rod; one end of the first rod It is fixedly connected with one end of the second rod, and the connection between the first rod and the second rod is fixed in rotation on a first plane that can move vertically relative to the guide plate; the guide plate is fixedly connected with a mold, and there is a A guide groove, the guide groove forms a certain angle with the vertical direction, and the top of the guide groove is inclined away from the second rod, the guide pin is arranged in the guide groove and can move along the axial direction of the guide groove, and the guide pin and the first The other end of the rod is rotatably connected, and the other end of the second rod is fixedly connected to the core-pulling part in the mould. The invention uses a simple structure to convert the vertical motion into arc motion, so as to realize the core pulling of the mould.
